Powerextra 2 Pack Replace for Sony NP-F750 Battery for Sony NP-F730, NP-F750, NP-F760, NP-F770 Battery and Sony CCD-TRV215 CCD-TR917 CCD-TR315 HDR-FX1000 HDR-FX7 HVR-V1U HVR-Z7U HVR-Z5U Camcorder

love this brand I can always rely on them. I dont have any big brand (sony) NPF batteries to compare to but these things can run my small led light panels for a long time. I bought a pair three years ago and one finally started having issues (makes the lights flicker). They have withstood a lot of charges and damage. Good quality. Bought another setUpdate - also had a battery fail within a year. So its hit or miss on the quality. Overall bought 6 of these batteries and 2 have failed over the course of 5 years.

I got this for my Led lights. I have a pair of old yongnuo 300 leds lapms. With this batteries they last for a bit over 2 hours

I like the size of these because they don’t weigh down the back of my HDMI monitor (unlike larger batteries I’ve tried). Good capacity and duration. No complaints.

A good alternative to the OEM batteries. I regularly buy the Powerextra batteries when I need replacements - because they are very reasonably priced and (in my usage) seem to last just as long as the OEM batteries.

bought 6 months ago just now there was a shoot, worked fine

I love the battery works great

My LED ring light uses Sony NP-F550 to 950 batteries. I decided to get the PowerExtra NP-F750 to increase the working time for my lights. A F550 only lasts an 2 hours at 100% light output before they drop dead. WIth the F750's fully charged, I ran my lights for 2 hours and plugged it into the charger which shows 56% and 51% remaining. If the LED light discharge is linear, then the 5200mA rating on these batteries are indeed double the capacity of the F550's which are 2600mA and will give me 4 hours run time. These are double the size of the F550's in order to get the continuous run time I need without having to change batteries.

At first, I was concerned about battery life as I would use them in my camera monitor for a short period and then turn off the monitor until the next day. When I attempted to turn on the monitor, the batteries were dead. After checking with the manufacturer of the monitor, I found that it continued to draw power even when in the off position. Now I remove the batteries and haven't had any problem with short life since.The larger capacity of these particular batteries adds to the weight of the entire rig (Ronin-S, Full-size DSLR, Lens, and monitor) but the extra life is worth it.
